Construct - Don't rely on measurements from protractor or ruler; you use only a compass and straightedge.
Draw - Carefully and accurately make a triangle using your protractor and ruler.
Duplicate - To copy using construction tools.
Sketch - Use freehand to draw a triangle; Don't need geometry tools.
3.2
Segment Bisector - A line, ray, or segment that passes through the midpoint of a segment.
Median - The segment connecting the vertex of a triangle and the midpoint of its opposite side.
Midsegment - The segment that connects the midpoints of two sides of a triangle.
Perpendicular Bisector - A segment bisector that is also perpendicular to the segment (a plane has only one).
3.3
Altitude - A segment from a vertex to the opposite side or to a line containing the opposite side that intersects it at a ninety degree angle ; its for a triangle.
Distance from a point to a line - This length is understood to be the length of the perpendicular segment from the point to the line; this is the shortest distance.
